Offers the best support, moisture protection and sound absorption for your floors.

ADVANTAGES

• • Reduces floor noise by providing excellent sound absorption

• • Provides cushioned comfort under laminate and floating wood floors

• • The Silencer SR™has high density and compression resistance properties that enable your floor to perform to its fullest potential and last a lifetime

• • The moisture barrier film and tape strip combine to lock out moisture and allow for quick and easy installation

• • Eliminates minor subfloor imperfections

• • Contains ultra•fresh™ anti-microbial which resists mold, mildew, and bacteria

• • The Silencer SR™ adds insulation value with an R-value of .205

• • Suitable for use with radiant heat flooring systems

• 100% recyclable, environmentally friendly, non allergenic and odorless

APPROVED SUBSTRATES

• • Dry, completely cured concrete (at least 14 days old with HVAC operating)

• • 3/4″ interior plywood or OSB flooring

• • Waterproofing and crack-isolation membranes

• Cement backer units

FLOOR PREPARATION

• • Subfloor should be clean and dry

• In geographic areas where concrete subfloors are subject to excessive moisture, a calcium chloride moisture test is required. Vapor emission readings in excess of 4 lbs. per 1,000 square feet in 24 hrs will require additional protection such as concrete sealant or polyethylene sheeting.

INSTALLATION Quick and easy installation* – requires no additional seaming tape, cuts with a knife

1. 1. Install The Silencer SR™ with film DOWN on subfloor

1. 1. Roll out underlayment with tape strip next to wall. Roll out next row in same manner butting underlayment close to first row ( do not overlap ) and covering the moisture barrier film. Remove the tape strip and secure the overlapping moisture barrier film.

SOUND ABSORPTION PROPERTIES
Impact Insulation Class (IIC) This method is to measure the impact sound transmission performance of a floor-ceiling assembly (sound transmission through the floor)
IIC – Flooring – Sub-Floor
70 – Laminate/Engineered – 6″ concrete with ceiling assembly
59 – Hardwood – 6″ concrete with ceiling assembly

Sound Transmission Class (STC) This method is to measure the air-borne sound insolating property of a partition element for effectiveness in blocking sound
STC – Flooring – Sub-Floor
71 – Laminate/Engineered – 6″ concrete with ceiling assembly
53 – Hardwood – 6″ concrete with ceiling assembly

Delta IIC The db rating difference between a floor measured with an underlayment and with no underlayment
Δ IIC 22
